Or course, thats always the case. If your state allows you to own an AOW( any other weapon) then its not an issue. Pay the 5.00 tax stamp and be legal.It would be wise to check your State Laws before purchasing a cane specifically designed as a weapon. In Oklahoma it is illegal to carry a "loaded cane". I have been told that this would be a cane weighted on one end or the other making it more useful as a weapon.
It would be covered under the CHL unless the state specifically prohibits it.
